The app will display blood glucose levels on an Apple Watch, according to CNET, by using a sensor strapped to the user's stomach. The sensor takes a glucose measurement every five minutes and sends it along to the Apple Watch. The app is expected to debut in April.

Previously, the Food and Drug Administration had higher regulations for blood glucose software, but the app will be merely reporting the information from a medical device so it would be excluded from Class III regulation (the tummy sensor manufactured by DexCom would still be a Class III device and need the highest regulation.)

The new app would be a boon for diabetics who must monitor blood sugar. They would simply glance down periodically at their Apple Watch for a blood glucose update without messy finger-pricking and blood testing. Still, we would have to wait to make sure the sensor and the app work well before suggesting diabetics get rid of their diabetic supplies.
